	 * @ngdoc service

	 * @kind function
	 *
	 * @description
	 *   The input is sanitized by parsing the HTML into tokens. All safe tokens (from a whitelist) are
	 *   then serialized back to properly escaped html string. This means that no unsafe input can make
	 *   it into the returned string, however, since our parser is more strict than a typical browser
	 *   parser, it's possible that some obscure input, which would be recognized as valid HTML by a
	 *   browser, won't make it through the sanitizer. The input may also contain SVG markup.
	 *   The whitelist is configured using the functions `aHrefSanitizationWhitelist` and
	 *   `imgSrcSanitizationWhitelist` of {@link ng.$compileProvider `$compileProvider`}.
	 *
	 * @param {string} html HTML input.
	 * @returns {string} Sanitized HTML.
